True relationship between tricuspid annular motion and velocity displacement components: Potential role in assessing right ventricular decoupling

Background Although measures of longitudinal displacement of the tricuspid annulus measured by M‐mode as tricuspid annular systolic plane excursion (TAPSE) and systolic velocity by tissue Doppler imaging (TA TDI s) are routinely used for assessment of right ventricular (RV) systolic function; these...

Zusammenfassung:	Background Although measures of longitudinal displacement of the tricuspid annulus measured by M‐mode as tricuspid annular systolic plane excursion (TAPSE) and systolic velocity by tissue Doppler imaging (TA TDI s) are routinely used for assessment of right ventricular (RV) systolic function; these measures describe different phenomena and should not be used interchangeably. Methods Previously published data was used to determine the individual relationship between TAPSE and TA TDI s with increasing pulmonary artery systolic pressures (PASP). Results In this retrospective analysis, 488 patients were divided into 2 groups based on TAPSE (Group 1:
